Arduino SMART CAR | Bluetooth Mode+Obstacle avoiding+Voice Control

Hello Friends💙 ;
This is my Project 05 in Arduino.
In this video, we will learn how to make a multi-functional robot using the Arduino platform. That is, includes obstacle avoidance, Bluetooth control, and voice control functions.
OK enjoy it now.

බුදු සරණයි මගේ පුතේ හොඳ ලස්සන වටින වැඩක්❤

[saidevs-thb]

good video bro but the 3 modes working in same time? and you put include three modes in this code

[javierrosendoarizu]

Hello. I have problems to download de arduino code and the schematic. How can I do it?

[somnathjana]

Sir I just want to ask one thing... for every different mode we have to upload the code every time...one by one...Is this possible that we can upload the code once to arduino uno and it follows the 3 methods (modes) which are bluetooth control, obstacle avoiding, voice control.

[saidevs-thb]

bro my one channel of l293d motor driver is not working why ?

[traiongxuan]

Can you tell me what command do you use to make your car's sensors turn in the direction you control?

[RinconMisterioso]

What if I activate Bluetooth mode and obstacle mode at the same time, does the car work in both ways?

[Aashutoshkumar-xuzy]

Sir which you using for controlling car?

[kshivappa]

hi, your circuit diagram is not able to open, can you resend in pdf form not in google drive.

[GB-edits]

Sir is there any way i can use the every code at same time

[WandimmuuAsmaamaw]

the file needs password to extract
what shall i do

[friendu]

Bro how to download your program it's only shows picture of circuit diagram

[AbhijithGs-yq]

bro at the second line of the code error is there can you verify it send the new code

[konakhatun]

Vai yeah kam nahi ho raha...servo ka library to inshtall kya je lekin firbhi yeah ho nahi raha....plz help kijiye vai ...servo motor ka librery file dijiye

[suvankar]

How can I change car speed specified in this code??? Please reply

[DhanjoyGarai]

Please 🥺🙏 give the code description please

[leewa]

What software do you use for voice control?

[suvankar]

Can I implement three things simultaneously?

[yvonneafonso]

Hi bro can u tell me how to download AF motor library and how to make the F led and the B led pls and also can u tell me if i can make the arduino do all the three programs with only one arduino


Thanks
